RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1964 (DGR)
STATION WAS RECOVERED AND ALL MARKS FOUND IN GOOD CONDITION. A COMPLETE DESCRIPTION FOLLOWS--
STATION IS LOCATED ABOUT 1-1/2 MILES NORTH OF WAIANAE ON THE PROMINENT RIDGE NORTH OF THE TOWN, AT A POINT ABOUT 1312 FEET ELEVATION.
TO REACH STATION FROM THE POST OFFICE IN WAIANAE, GO NORTHWEST ON FARRINGTON HIGHWAY FOR 1.7 MILES. TURN RIGHT AND GO NORTHEAST ON MAIUU RD. FOR 0.3 MILE TO T-JUNCTION OF KAUIAWAHA RD.

Control Text

The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in December 1998. The horizontal coordinates are valid at the epoch date displayed above. The epoch date for horizontal control is a decimal equivalence of Year/Month/Day.

The orthometric height was scaled from a topographic map.

The Laplace correction was computed from DEFLEC99 derived deflections.
